To coZZ whom, it may concern:

Be it known that we, ORVILLE R. SAGKETT and PHILIP J. KELLER, citizens of the United States,residingatNiagara Falls, in the county of Niagara and State of New York, have invented new and useful Improvements in Fire- Extinguishers, of which the following is a specification.

This invention relates to improvements in fire-extinguishers, and more particularly relates to a construction of such devices which is adapted to be employed in connection with hosewagons and vehicles of an analogous character.

The objects of the present invention are to provide an improved construction of fire-extinguisher wherein is contemplated such an arrangement as will insure perfect discharge of the acid into the soda solution; and, furthermore, the invention has in View the provision of novel means whereby one of the sodasol ution-containing tanks may be readily recharged, after being emptied, While the other tank is being discharged.

With these and other objects in View, which will appear as the nature of the improvements is better understood, the invention consists, substantially, in the novel construction, combination, and arrangement of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a hose-wagon equipped with the herein-described extinguisher. Fig. 2 is a rear end elevation of the extinguisher removed. Fig. 3 is a vertical longitudinal sectional view through one of the soda-solution-containing tanks. Fig. 4 is a transverse sectional view on the line 4: 4 of Fig. 3.

Referring to the drawings, the numeral 1 designates a hose-wagon, which may be of the usual construction, and extending along each side, over the body thereof, is a cylindrical tank 2, removably seated on the hose-wagon through the medium of brackets 3, arranged at suitable intervals. These tanks overhang the rear end of the wagon-body for a purpose hereinaftendescribed. As illustrated in the drawings, the tanks 2, as before stated, are employed in connection with a hose-wagon;

but it is perfectly obvious that, if desired, the extinguishing mechanism maybe used in connection with a hook and ladder.

The tanks 2 are adapted to contain soda so; lution, and each of said tanks is provided at its forward end with an upwardlyextending dome or receptacle 4:, provided at its extreme upper end with a neck 4?, having a series of exterior screw-th reads 5. Mounted upon said threaded neck 4; is a removable cap 6, which cap is provided with integral screw-threads 7, adapted to engage the threads 5, and depending from said cap 6 is a yoke 8, which is suitably connected to and carried by the cap 6. The yoke 8 is provided at its lower end with an upwardly-extending plug 9, which serves the purpose of a stopper for an acid-receptacle 10, the normal position of which is inverted, as shown, so that the plug 9 is adapted to fit within the mouth thereof. The receptacle 10 is provided at its upper end with a supporting-plate 11, suitably connected to said receptacle, and said plate is swiveled to an adjusting-screw 12, which passes cent-rally through the cap 6, the screw 12 terminating at its upper end in a hand-wheel 13, by means of which the screw 12 may be easily rotated. By this construction it will be seen that upon rotation of the screw 12 so that the latter moves upwardly the receptacle l0 follows its movement, and thereby recedes from the plug 9, whereupon the acid contained in the receptacle 10 discharges into the soda solution contained in the tank 2, and by reason of the acid eomrningling with said soda solution a high pressure of carbonic-acid gas is generated.

Arranged in the rear end of each of the tanks 2 is a longitudinally-extending shaft 14, journaled in suitable bearings consisting of a spider-fra1ne 14 and end cap 14*, and mounted upon said shaft 14 is a series of radially-extending agitatorblades 15. The shaft leis provided at its rear end in a crank 16, by means of which said shaft is rotated, and by reason of said rotation the soda. solution is thoroughly agitated and the acid when discharged thereinto fully intermixed therewith.

27 represents intermediate valves controlling the horizontal pipe 28.

In order that the carbonic-acid gas when generated and the liquid maybe led oif from the tanks 2, each of the latter is provided at a point in rear of the receptacle 4 with an inwardly-extending perforated nozzle 17, and each of said nozzles has connected therewith an outlet-pipe 20, which pipes extend transversely of the vehicle and are connected at a point midway thereof with a T-head 21, to

which latter a hose is adapted to be attached.

It will be observed that the head 21 projects upwardly through the bottom of abasket 22, and said basket is adapted for carrying the hose above referred to. It will also be observed that each of the pipes 20 is provided with a valve 23, whereby the flow of gas from the tanks 2 may be cut off in order that, if desired, only one of said tanks may be dis? charged at a time.

Arranged at the rear end of each of the tanks 2 and depending therefrom is a pendent pipe 24, in which is located an upper valve 25, and each of said pipes 24 is also provided at its lower end with a similar valve 26, a hose connection 27 being arranged immediately above the valve 26 for a purpose to be presently stated. Extending transversely to the vehicle and connecting the pipes 24 is a horizontally-arranged pipe 28, whereby communication between the pipes 24 may be effected. Each of the tanks 2 is also provided with a pressuregage 29 for indicating the amount of gas contained therein.

In use the tanks 2 are filled with soda solu tion and the receptacles 1O likewise filled with acid and introduced into the receptacles 4. Prior to the latterintroduction, however, the domes or receptacles are properly closed with the plugs 9 in order to prevent the escape of the acid into the soda solution until the required time, and after this has been accomplished said receptacles 10 are inserted into the receptacles 4 and the cap 6 secured upon the latter. When it is desired to discharge the acid into the soda solution, the screws 12 are manipulated as hereinbefore described, whereupon the discharge of the acid into the soda solution takes place, and thus generates a high pressure of carbonicacid gas. By the rotation of the agitatorblades 15 thorough commingling of the acid with the soda solution is had, and when it is necessary to discharge the gas for extinguishing purposes the valves 23 are opened. The gas immediately rushes through the pipes and the hose connected to the T-head 21 and may be directed to points where it is required. If, however, it is desired to discharge one of the tanks 2, it is obvious that only the valve 23 thereof will be opened, and the supply of gas in the other tank is thus held in reserve.

Should it be desired to recharge the discharged tank while the tank remaining charged is being discharged, the same may be effected by closing the lowermost valve 26 of the pendent pipe 24, connected to the discharged tank, and opening the valve thereof. By attaching hose to the connection 27 and opening the valve 2'7 water may be forced through the pipe 24into the empty tank 2, and inasmuch as the valve 25 of the pipe 24, connected to the tank which remains charged, is closed it is apparent that none of the water being forced into the empty tank will be admitted into said charged tank. In so charging an empty tank it is of course necessary that the receptacle 10 thereof should also be recharged with acid, and this is effected by. simply removing the cap 6, through which movement the receptacle 10 is also removed and adapted for recharging.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is

l. A fire-extinguisher comprising a pair of horizontal tanks adapted to be arranged on opposite sides of the body of a wagon and adapted to contain soda solution, each tank consisting of a cylinder having a dome at its inner end formed with a screw-threaded neck, a spider-frame located within the cylinder, and a cap to the cylinder providing shaftbearings, a shaft having radial agitatingblades and mounted in said shaft-bearings, a screw-cap for the dome provided with a pendent yoke carrying a plug, an inverted acidreceptacle adapted to seat on the plug and havingasupporting-plate,an adjusting-screw working in the cap and swiveled to the supporting-plate, discharge-pipes having valves and connected with the cylinders and a T- coupling connecting the discharge-pipes and providing a hose-coupling.

2. A fire-extinguisher comprising a pair of horizontal tanks adapted to be arranged on opposite sides of the body of a wagon and adapted to contain soda solution, each tank consisting of a cylinder having a dome at its inner end, a spider-frame located within the cylinder, and cap to the cylinder providing shaft-bearings, a shaft having radial agitating-blades and mounted in said shaft-bearings; an acid-receptacle located within the dome, discharge-pipes having valves and connected with the cylinders, a T-coupling connecting the discharge-pipes and providing a hose-coupling, the pipes depending from the front end of the cylinder, each provided with lower, intermediate, and upper valves and a horizontal connectingpipe, coupling the depending pipes providing hose connections and controlled by the intermediate valves.

In testimony whereof we affix our signatures in presence of two witnesses.
